fly line question -- a matter of tapers

Hey-

I'm always interested in trying new fly lines, it amazes me how differently they can cast.

I am now after a new floating line and I'm interested in the so-called "quick-loading" characteristic of redfish tapers.

Does anyone know how a Cortland Redfish taper might differ from a Rio Clouser taper (also said to be "quick loading")? I know that cortland taper is heavily concentrated in the front end ( with a body of only 18' and a front taper of 3'), but the clouser has a longer body, yet a different taper altogether.

Can anyone weigh in on these two lines?

cheers!
